IMPROVEMENT IN MACHINES FOR MAKING COUPLING-PINS.

Specification forming part of Letters Patent No. 1] 0,179, dated December 13, 1870.

To all whom it may concern Be it known that I, CHARLES H. WILLIAMS, of Cleveland, Gnyahoga county, in the State of Ohio. have invented certain new and useful Improvements in Machines for Making Coupling-Pins for Railroad-Oars; and I hereby declare the following to be a full and exact description thereof, reference being bad to the accompanying drawings forming part of this specification.

The nature of my invention consists in the particular construction and arrangement of the devices described in the following specification and represented in the drawings, for making coupling-pins for railroad-car couplin s.

l n the accompanying drawings, Figure 1 is a plan or top'view of a. machine with my improvements for making coupling-pins for railroad-cars and other articles. Fig. 2 is a section to the right of the line z 2, Fig. 1. Fig. 3 is the left-hand side of the machine. Fig. 4 is the right-hand side. Fig. 5 shows a coupling-pin in its successive stages of manufactore.

In these drawings, A is a cast-iron bed-plate or table, which may be made in the form shown, or in such other form as will answer the purpose, and provided with journal-boxes B B for the shaft 0, which may be provided with a pulley or gear to turn it and operate the machine. On the left-hand side of the plate A I make the flange D, and on the left side of the flange the lugs E and F, for seats for the dies G and H, which are fastened by the plates G and H, as shown in the drawing, Fig. 3. I is a. traversing yoke with a slot in-it, fitted to traverse on the lug and provided with flanges J J. arranged to traverse under the cleats J J, when it is worked by the link 1, which connects it to the cam I on the shaft 0. This yoke I has the die G fastened to it by the plate G, which die corresponds with the die G, to taper and form the points of the pins, as shown in Fig. 5 of the drawings. The die H is fastened in the end of the yoke I by the plate H whichdie H corresponds with the die H, to swage the ban die or top of the pins flat, as shown in Fig. 5. On the top of the plate A I make the lug K, to form aseat for the die K, which is fastened by the plate K, secured by bolts. -At the lower lurch-and corner of the plate A I make the log I), with a groove under its upper edge for the flange on the traversing block L to traverse in. This block has a flange on the opposite ed go, which traverses under the edge of the guide-block M, which is fastened to the plateA by bolts. as shown in Fig. 1. The block L carries the (lie K, which is fastened to it by the plate K, and corresponds with the die K, and both are grooved, to clamp the shaft N of the pin and hold it while a. portion of it is upset to form the head or collar N, the lower bnltiof the collar being formed in the countersink in the dies, as shown by dotted lines in Fig. 1. The traversing slide P, which works against the inside of the flange D, is held in position by a flange traversing under the edge of the block M. This slide P has its-forward or lower end inclined, to corre spend with an incline on the block L, so that when the slide P is pushed down by the cam P on the shaft 0 the block L and the die K are moved toward the die K, to clamp and hold the shaft of the pin, asbefore mentioned. The heading or upsetting die Q is fastened in its stock Q by the plate Q. This stock is fitted to traverse on the plate A, and has a flange on each side, one of which works under the edge of the block M, and the other under the edge of the guide-block M, fastened to the plateA, and it is pushed lorwarlhto carry the die Q down to the dies K and K, by the cam Q on the shaft 0, and is forced back by the spring Q acting against 2. lug on the side of the stock Q. The slide P is drawn back by the rod P and spring P fastened to the plate A, and the block L is drawn back by the spring L, fastened to the log L, as shown in the drawing.

When the slide Q is thrown back by the spring Q, it is stopped by the adjusting-slide M, fastened to the block M. By adjusting this slide M the slide and die may he stopped, so as to graduate the quantity of iron put in the collar N. After the collar N has been formed on the pin, the dies open and the pin drops down-through the opening M in the plate A, and rolls out at the right side of the press, to be further manipulated.

The devices for swnging the neck or handle 3 ll0.l79

and punching it are shown in plan, Fig.1, and in elevation, Fig. 4. I make a flange, R, and lugs R and R, to project up from the righthand side of the lug K, and the lugs R and R are perforated for the pin R, which forms the fulcra of the levers S and S. which are raised by the cams S and S on the shaft C, (shown by dotted lines in Fig. 4,) and these levers are drawn down or against the cum by the spiral springs S and 8, fastened to the plate A. On the right-hand side of the ma chine or frame I make a log, T, to form seats for the die T, which is held in place hy the late T, and also for the die V, which is held in place by the guide-rest V'. The traverse slide or die-box W is titted to traverse between the lugs U U on the side of the flange R, and is worked by the lever S, fitted onto a stud in the hack of the slide W. This slide W forms the seat of the die V, which is fast eued to it by the plate V. The dies V and V are clampingalies, which press the handle N of the pin, and keep it flat, while the dies T and '1 swage or compress and narrow the neck of the handle, as shown in No.- 3, Fig. 5, and remain closed around the handle, while the punch V descends and punches the hole in the handle and finishes the pin. The die T hus its seat in the traversing slide X, and is fastened to it by the plate T. This slide traverses between the cleats X X, and is worked by the link X, which connects it to the cam X on the shaft U. (Shown by dotted lines in Fig. 4.) The slide W has a. recess or groove in its upper end, in which the block Y is fitted to traverse, and is worked by the lever 8' on a stud in the side of the block. The dies V and V are perforated for the punch V, which is fastened in the block Y, and worked by it-,sn as to punch a hole in the handle N after it is necked, and while it is clamped by the dies V and V.

To make coupling-pins or breech shackle- 'pins for cannon l take a round bar of iron of the proper size and length, and heat one end, and put it between the dies G and G to swage the point, and after the dies have closed once upon it and opened, I turn the bar one-fourth the way around and allow the dies to close on it again, which completes the point. I then heat the other end, and put it between the dies H and H to flatten the end for the handle, and while it is still hot I put the flat end or handle up between the dies K and K, into the socket in the die Q, which socket is formed to lit the flattened endand preserve its shape, while the dies K and K clamp the har,and the die Q moves down onto the clamping'dies and upsets the bar, or that portion of it that is between the ends of the clampingxlies and the die Q, and forms the head or collar N in the countcrsinhs in the dies, as shown by dotted lines in Fig. I, when the (lie Q, draws hack ofi'of the head and handle, and the clampingdies open, and the pin falls down through the hole M, and rolls out at the right side of the machine, where it is picked up, and while the head is still hot the handle is thrust in hetwcen the dies V and V, which clamp it and hold it flat, whilethe dies T and T swage and narrow the neck oi'thc handle, and the punch V descends and punches the hole N in the handle, and finishes the pin.

I claiin The above-described machine for making coupling-pins for railroad-cars, provided with the dies H and H, for flattening the handle, nnd the dies Q and K and K, for forming the header collar, and the dies V and V, and the dies T and T and the punch V, for necking the handle and punching the hole in it, substantially as descrihed.
